ceased .lipplieatnm July a4, 1939, serial No. 2116.049 is claim. (o1.49-9) The present invention comprises a glass machine. It has particularreference to a forming 4machine that receives molten glass in which theglass is shaped into articles.

The machine is particularly applicable totheV manufacture of ware formedin twomolds, the

first called the blank or parison mold, and the second called the finishmold. Asl shown in the illustration, the machine is applied to containerware.

Fig. 1, the section line being broken back tov show i In general, it-maybe said that the machine includes a central column about which variousmechanisms rotate. The mechanisms may. be

. divided into the blank stage and the iinishing stage, which are ondifferent so-called tables supported about the column. Each table has onit a plurality of molds disposed so that they represent successiveoperations taking place in the forming of the glass.

The two'mold sets are so disposed relative to.

each other that when 'the parison is finished on the one table. it canbe transposed very readily to vthe nish ,molds at a proper station onthe other table, for which a suitable transfer mechanism is provided.

There is also provided a ware take-out device which removes nished warfrom the last station to the finish molds and transfers` it to asuitable performing all of its operations while in motion,V

so that time is not lost between intervals of processing, as customaryheretofore.

Further objects are the provision of a machine in which a plurality ofmolds are provided, adapted to receive glass successively, and torepresent progressive stages of processing of the glass, whichprocessing takes place in continuous operation. Also there is a machinemoving about a single column `having molds thereon of both a bafiieplate mechanism for a mold corresponding with the blow mold shown, butotherwise being diametrical. i

bevel gear 44, and with it the pinion 4I and unally the ring gear 43. Itwill be seen that thereis a'sreat speed reduction through this gearingfrom the drive shaft 41 to the ring gear 40, and the drive shaft 41makes one revolution each time the ring gear moves the angular distancebetween adjacent stations on the tables. v

The drive shaft 41 operates through a clutch The clutch is a one wayclutch and engages at only one point so as to insure proper timing. Thusthe drive shaft can engage only when the mold tables are in a suchsynchronism as will have a mold properly' positioned to receive a chargeof glass from the feeder and shears.

Base structure and drive mechamsm The machine has a base 30 tha restsupon a solid oor. 'I'he base has thereon an upstanding circular track3l. A circular frame 32 has flanges engaging over the track 3i tosupport it thereon. As shown in Figs. 2 and 4, spaced ears 33 projectoutwardly from one edge of the frame 32 and receive pivotally betweenthem one end of an adjusting screw 34, the other and threaded end of'which passes through opposed ears 35 on the base 30. An adjusting nut 36'is located betweenthe two ears 35' and is threadedV .on to the drivenfrom some suitable source of power, as for mounted in a housing 61projecting from the side of the frame 32. mechanism i.; inconsequentialalthough the drive A should permit adjustment of -the frame 32 about thebase 3l), as will be. the case if the motor is'v mounted on the frame32.

" Thus 'it may bey seen that the power mechanism screw 34. By this meansdisplacement of the" frame 32 relative to the base 30, inthe vform ofrotative movement about the track 3l to a lim ited degree,canbeeilected.l

A web 31 extends within the circular flange part of the frame 32'. Fixedto the web 31 is an up-l standing hollow column 38, which column is themain support'for several of the mechanisms of the glass machine.A Y

The frame 32 has a circular channel 33 opening upwardly and in whichthere is located a ring gear 40. The ring gear is rotatable within the,

'circular channel (in suitable lubrication). and

l f cess to the interior of the housing.

The pinionu is keyed to a. bevel gear u that, in-turn,l is fixed to acountershaft 45. 'Ihis v1(iii by the clutch 5|, and synchronously gearoperates the valves. Y

A main table 10 is fastened by screws around with the ring the upper endand projecting edge of the ring .which are mounted the transfermechanisms and blow down heads, to be described.

An extension of the table 10 is displacedsomewhat above the horizontalflange 10b and consists of an inwardly directed table 10c. The portion10c may generally be indicated as the blank `mold supporting table. Thisportion has a large circularopening in theA center through which thecolumn 38 extends. It will be clear that when -the ring gear 40 rotates,the entire drum 1li rotates with it.

From the inner part yof the table portion 'llc there extends upwardly aninner` drum portion 15 which is integral with the portion 10c. Thiscountershaft is journaled in the frame 42 in bearings as indicated. Ahorizontal drive shaft 41 is iournaled in the'frame at 48 and has keyedthereto a beveled driving gear 4 3 that drives the iirst portion 15 isanged at the bottom as' at 13. At

spaced intervals around the column 15, and one for each station, aredisposed ears 11 opposite the ange 15. Above the horizontal ears 11 is aflange "lllhe drum 15 has an inturned a'n'ge 83 The 'I'he type ofparticular power I movement radially of the machine.

is bolted to a sleeve al (Fig. 2 that bearsretetably on the column 38.

Blank molds I tions 86 and 8 1 (Fig. 12). The mold sections are hingedtogether, section 86 having spaced hinge varms 88 and 89,` and 4thesection 81 having the hinge armv 90, a hinge pin 9| passing down throughthem. This hinge pin likewise passes through spaced ears 92- and 93,projecting out from a bracket 94 bolted between the flanges 16 2 and11on the drum 15.

The mold section 86 hasan ear 95 thereon to which is pivoted a link 96that in turn is -pivoted to a crank 91 ilxed to a shaft 98, The shaft 98nts within a sleeve 99 that is carried by the horizontal portion ofthe'table 10c. A crank |00 is secured to the lower end of theshaft 98andis substantially identical with the crank 91. It has ears that receiveone end of a'link |0| for pivotal movement, the other end of this linkbeing received pivotally in one end of one arm |02 of a forked plunger|03. The other arm |04 of the forked member is attached by means of alink to a crank arm |06secured to a shaft |01. This shaft, in a mannerlike the shaft 98, operates a crank |09 connected by a link' ||0 to anear on the other mold-section 81. I 'I'he plunger |03 passes through asleeve ||5 and has a nut||6 on the end thereof. -Within the sleeve thereis-a reduced portion surrounded4 4 bya spring ||1 that normally urgesthe member |03 -outwardly relative to the sleeve 5. 4The vupper edge ofthe sleeve is provided with a T member ||8 (Fig.` 10) that rides freelyin tracks 9 bolted to the under side of the table 10c for Depending fromthe lower part of the sleeve ||5 there is secured a cam roller |2`0.This cam roller is engaged by a cam |2,l1 that is clamped about thecolumn 38 by a releasable screw |22 Loosening of this screw permitsadcam lhas a portion |26 at a constant radius; a portion |28 at anincreasing radius; a lportion |21 at a constant outer radius; and aportion |28 at a decreasing radius. A flanged element |29 is bolted tothecamcpposite the portionv |28 so as to engage the roller in its outerposition and direct it toits inner'position on the portion |25.

It will be clear that as -the mold sections are rotated on the tablearound the column, the

' roller|20 of each one will be carried inwardly o'r outwardly by thecam. Inward movement will be seen to open the molds and outward movementto close them. In closing, any excess movement of the sleeve ||5, beyondthat permitted by the closing mold sections, will be absorbed in thespring ||1. Each mold section has a neck ringl receiving cavity |36.There are two neck ring halves" forr 7 each mold, one fitted into eachof the two neck ring cavities. These neck rings constitute part of thetransfer mechanism to be described and hence are separable from the moldsections.

When the neck rings |36 are inplace, as in 7 Fig. 8, in the parisonmold, they t within the bottom of the mold and have an internal shapethat is of the nishf ofthe bottle to be made.

There is also a taperedl plunger-receiving portion within the rings.Where the shape of the finish is changed, then different rings areinserted into the neck ring holders. The neck ring holders t down overan upstanding and undercut annular portion |31 on the block 84. Thisportion |31 is opposite the depending portion 85. A

Slidable in the portion 85 is a plunger stem I3 which has in the topthereof a removable plunger plug |39. The plunger is removable so thatdifferent sized ones may be used for different ware.

this, in turn, communicates with a pipe or con-L.

The plungers pass through the portion- |31; and there are passages |40between the plungers and the walls of the portion |31. The fit of theupper and cylindrical part of the plunger |39 into the tapered part ofthe neck rings permits vacuum to be drawn in the mold.

'I'here is -a chamber |43 into which the passages |40 communicate, andwhich surrounds the upper part of the plunger stem |38. An air passage|44 in the block or bottom plate 84 communicates with a passage |45 inthe table 10c and duit |46 that leads to an air distribution manifold,to be described.

The plunger |39 reciprocates from a lower pesitionwherein it does notproject into the neck rings tothe position of Fig. 8 wherein it is up intheneck rings. This action is produced by the engagement of a camrolieron a shaft `|41 fitted into the bottom of the stem |38 and engaging in acam track |48 secured to a cam disc |49 clamped to the column 38 andadjustable therearound.

As will be understood, at the proper time when a gob of glass has beendeposited in the parison mold, a vacuum is applied around the plunger|39 and into the bottom of the parison mold drawing the glass downwardlyto be compacted into the parison mold and to form the nish.

.In order to direct the plunger into its upward Transfer mechanism.

The transfer mechanism is mounted on the table 10b and rests on arms |60extending outwardly.' therefrom. 'I'hesemarms also support bearings ofthe finish mold'nechanism, to be described. Stanchions |6| and |62 aremounted on the two arms and each constitutes a bearing support. A- yoke|63 has bearing portions |64 in the stanchion |6| and |65 in thestanchion |62. 'I'he yoke has |61 disposed radially of the machine, andsupporting a shaft |68. One of the neck ring holders has spaced arms |69and |10 that embrace an `arm |1| on the other neck ring holder. Thesearms are hinged on the shaft V|68 between the branches |66 and k|61 ofthe yoke |63. tending from the-v side oi each neck ring holder arm thereare spaced bosses |13 slotted'as at |14. A forked member |15f.has twopins |16 engaging in the slots ml 14. The shank-of this forked memberhas gekggggeth thereonat |84 and this shank bears and'refprocates in asuitable opening |11 through the yoke |63.

|5|v extend arcuately over the distances opposed branches |66 and Asegmental gear |18 is mounted on a stud shaft |19 supported in opposedears |80 (Fig. 11) on the yoke |63. This gear |18 has a radialprojection |8I thereon, one edge of which is en- I gaged by acompression spring |82 that also engages against a projection |83 on theyoke |63.

Thus the gear |18 is always urged ina clockwise direction as is seen inFig. 9 to force the fork |18 to the right (Figs. 8, 16, and 17) whichacts to close the neck rings.

It may be seen that there are two operations involved in the actuationof-the transfer mechanism. One of these operations is the opening landclosing of the 'neck rings, and the other is the rotation of the neckrings from their position under the parison mold to their position overthe finish mold.

The transfer operation operatesthrou'gh a gear |86 keyed to the yoke|63. A housing |81 encloses Athe gear |86 and has an upstanding portion|88 thereon that receives andacts as a bearing for the rack |89 thatmeshes with the gear |88. This rack has on its inner edge a cam roller|90 engaging in a cam track |9I`, the shape of which is shown in Fig.15. It is evident that the displacement of the cam roller by thev track|9| lifts and lowers the rack |89 thereby oscillating the segmental gear|88 to move the transfer mechanism |80 from position in the parison moldto position over the nish mold'.

For opening and closing the neck rings, which l the cam |93.

As appears in Figs. 19 and 20, the two flanges 20| and 202 correspond inoutline. From their arcuate inner portions, they extend out and enlargein an arcuate shape to receive 'the cam web 204. There also are.provided bosses. 208 and 206 that are concentric with the arcuate camweb 204. They form bearings for a shaft 201, the

shaft being movable both rotatively and axially in the two bosses.

Supported on the shaft between its journals is an arm 208-attached .tothe shaft201 by means l such as a set screw 209 engaging in a groove onthe shaft to cause the arm to move with the shaft.

The `arm 208 is enlarged around the shaft 201 and projects end of theprojection backwardly therefrom at 2|0 and on the indicated at 2|2 inthe cam web 204. The slot 2I2 has an upper or starting portion 2 I3extending into a spiral portion 2 I4 that terminates in a verticalportion 2I8, the latter being at the bottom.

The opposite end of the arm 208 has a vertical opening therein throughwhich passes a screw 2 I8 (Fig. 21, sheet 9) free for axial displacementthrough the arm. A pair of collars 2I1 and 2I8 are threaded onto thescrew 2|6 and hold it in adjusted vertical position relative to the arm208. At the bottom of the screw there is secured the baille plate 220.

From the foregoing it may be shaft 201 is forced axially downwardly fromits position in Figs. 8 and 19, the arm-"208 willbe oscillated becauseof the action of the cam roller 2| in the slot 2 I2. This oscillationwill displace the baille plate outwardly away from the column 38 untilit is centered directly over its parison mold. At that time, the rollerwill be at the entrance of the vertical portion 2 |5 of the slot so thatfurther downward displacement of the shaft 201 will produce directvertical movement of the arm 208 and the baille plate 220. The bae platewill then seat securely over its blank mold;

Owing to the fact that in. the outer position of the transfer mechanism,the projection |8I is in contact with the cam |93, this rotation of thecam, as will be apparent from Fig. 12, will rotate the segmental gear|18 counterclockwise (Fig. 9) to open the neck rings. As soon as therocker arm |95 has passed over the pin |96, the spring |82 actingagainst the projection |8| will cause` the cam to return to its initialposition. If desired, a return'spring may be provided acting directly onthe arm |95.

Bale plate Thus far the construction of the blank molds y and the neckrings lfitting in their bottoms have been described. The baille platewill now be deA l scribed to complete description of the blank moldassemblies.

A supporting bracket -200 has an upper flange 'I 20| and a lower flange202 joined by a web 203.

The bracket 200 is located between the upper and lower flanges 19 and 18on the. drum 15. The

- connecting web 203 is arcuately shaped so asto fit snugly against thedrum; and the bracket is bolted between the two flanges mentioned.

There is a bracket of this type foreach of the stages and each bracketis disposed some degrees the bracktin'FigL8does'not cooperate with themold there shown,.but`rather with the one next behind the oneshown.

In order to get the above oscillation and axial displacement of thebaille plate, it is necessary only to apply the proper verticalmovements to the shaft 201. These movements are obtained by a pair ofcam rollers at the top of the shaft engageable at the proper time withcams.

The first-of theserollers 228 Ais attached to the top of the shaft inthe angular relationship shown .in Fig. l. 'I'he second of these cams224 is at- I tached'on a collar 226 secured to the top of the shaft 201.

At the top 'of the column 88 is located a cam table 228 secured' inposition by a set screw 221. An arcuate cam plate 228 is bolted as at228 to the table 226. As is seen, this connection is a bolt and slot'connection permitting displacement of the cam plate 228 arcuately foradjustment. The'plate 228, as appears in Fig. 8, is in^an elevatedposition over the cam roller 228. Its elevation first rapidly decreasesin a clockwise direction from its starting point, view in Fig. l. todepress the shaft 201 to cause` oscillation and lowering of the bailleplate. The cam plate then remains low, to provide a dwell of the balileplate,

counterclockwise from the parison mold with si willigh it cooperates-asappears in Fig. 1.- Thus,

and, at. its most clockwise end, rises again.

As .appears also in Fig. 1. beneath the major part o`f the plate 228 thecam 226 is cut away vat 280 so that the cam roller 224 may movedownwardly to what is normally beneath the table 228. At the end of thebaille plate interval and almost at the end of the arcuate cam plate228, the table 228 has its edge lowered to a point below the cam 2I0there is a cam roller 2| I. This cam roller engages in a slot, generallyseen that, if the asaaevs roller 224 in its depressed position, andbeginning at the I ast rise of the cam plate 228. This cam roller 224then engages upon the upper surface of this lowered part of the table226 and is elevated,

and along with it, theshaft 201. An elevated cam portion 23| acts on theroller 224 to bring the rounds a shaft 280 and rests at its lower endshaft 201 up toits starting position and to maintain it there. There isthus provided the proper vertical movement of the shaft 201 `tooscillate and seat the baille plate on top of the mold.

Finish molds nects this crank 280 with the mold section 251.

The finish molds will now be described and it i will be apparent thatthey in manyv respects operate similarly to the blank molds.

Radially outwardly from each blank mold station there is a iiat boss 240(Fig. 26) on the drum '10a. This boss has medially thereof a vertical ipinion 248 having a squared head 249 and which engages with the rack242. By loosening the nuts ol'- the screws 245, the engagement of awrench over the squared head 249 of the pinion 248 will permit rotationof the pinion lto move the mold yoke vertically. As will be seen,thiswill permit the mechanism to take care of molds of differentheights.

The mold yoke has an upper ange 250 and a lower ange and table The tableis shaped, as appears in Fig. 26, to accommodate the mold sections asthey move from open to closed position.

`A vertical mold-'pin 253- is supported between the anges 250 and 25|. Afinish mold` section 25d lhas two hinge arms 255 and 256 that arejournaled about the pin 253. A complementary mold section 251 has asingle hinge arm 258 fitting between the previously mentioned hinge arms255 and 256 on the -mold vsection 5253, and hinged on the pin 253. j

For opening and closing the mold sections the following mechanism isprovided. A sleeve 26| is supported in the drum 10a by horizontallydisposed brackets 262 (Fig. 24). Slidably supported inV this sleeve 26|there is a plunger 263 having two cam rollers 264 and 265 (Fig.` 14) atthe inner end thereof. The cam roller 264 operates against a push camedge 266, and the cam roller 265 operates against a pull cam track 261,both of these being secured Ito or as a part of the cam table 268 uponwhich is also supported the previously mentioned transfer mechanism cam|8|. `The table 268 is supported on aange on the main column 38.' 'I'heplunger263 receives the end of a, yoke 210 having diverging outer arms21|v and 212. A coil spring 213 operates in a, manner similar tothecoil. spring |1 toperrnit and cushion relative movements between theyoke 210 and the plunger 263, but

normally urging the yoke 210 toward its ma'xi-v mum outward position aslimited by the pin 214. A"second pin 215 holds the yoke against rotationby engagement in opposite slots 268' (Flam).

The arm 21| is connected by a link 216 to a upon a supporting bracket28| bolted to a flange 282 that extends around the drum 10a.

4'rhe upper ena or the sleeve 21a terminates just below a supportingjournal 283, mounted on anl extension of arms |60 on the drum 10a.

A second clamp crank sleeve 290 is clamped as at 28| about the sleeve218. A link 282 con- In a, similar way, the arm 212 is connected by alink 283 to a clamp crank 284 adjustably attached to a vertical rod 285.This rod is journaled in a bracket 286 bolted to the ange 282 andislikewise journaled at its upper end in a journal 281 mounted on theother arm |60. A clamp crank 283 is adjustably attachedA to the rod 285and is joined by meansof a link 288 to the mold section 254.

From the foregoing, it will be seen that reciprocation of the plunger263 oscillates the sleeve 218 and the rod 285 torotate the-'cranks 280and 288 and thereby to lcause the -mold sections 254 and 251 to hingeclosed or open about the pin 253. The ilnish molds are disposed out fromunder the-blank molds, giving access to them. from above, for repairsand replacements, and enabling the ware take-out to reach the glass.

Blow head The blow-down head 305 for' the i'lmsh molds is adapted to bebrought over the parison after the withdrawal of the neck rings. Thisblowdown head 305 is of a familiar type. It fits down over the nishofthe bottle that projects above the finish mold and has a tappet valve306 that is opened by contact with the glass. 'Ihis action admits airfrom the line 301 'into the blank to cause the same to ll out into thefinish. mold.

'I'he blow head is secured to the Ablow head arm 3I0 that is attached toa sleeve 3| I. This sleeve has a shoulder thereon against which the armis urged by a coil spring 3|2,` the other end of which is retained by acollar 3|3 secured to the shaft 280.

The shaft 280 extends through a cam housing 3|5 and is keyed thereto.This cam housing has a cam slot generally indicated at 3 I6, the camslot having a vertical portion 3| 1 and a spiral portion 3|8\(Fig. 25).A cam roller 320 is secured on the end of the arm 3|0 and rides in thecam slot 3|6.

It may be observed'that reeiprocation of the shaft 280 in the positionof Figs. 22 and 25 will rst vertically lift the blow head and then moveit back toward the vaxis of the machine to a position free of the -wareand the mold. In order to prevent jamming, but insure a tight fit of theblow head on to the mold, the spring 3|2 will permit some relativemovement between the arm 3|0 and the shaft 280, The shaft visreciprocated by avcam roller 32| secured at its bottom.. 'This camroller operates Wave take-ont` v'I'he ware take-out mechanism will nowbe describedi On the top -of the column 38 there isv a collar 330 thatis clamped as at 33| against rotation. From this collar there extends'radially ,anv arm` 332 at the outer end of which there is crank 211 thatis clamped about a vertical sleeve v 213 by a clamping bo1t-218. 'I'hesleeve 218 sursecured a depending sleeve 333.

Secured to the top o1' theflange .18, that is part ofthe drum15,thereisaninternalgear 334. This gear,'therefore, rotates .with therotation of the main drum 13. yA gear 335 meshes 333 that meshes with asecond ini-ter gear 343 keyed toa horizontal shaft 34| journaled inAspaced -bearings'342 and 343 in the arm 332.

The outer end of the shaft 34| has keyed thereto v a bevel gear 344 thatmeshes with a corresponding bevel gear 345 secured to a hollow shaft 343within the depending sleeve 333. This hollow shaft has secured to itsbottom end a head 341 having arms.,343 and 343. These arms are identicalso onlyone need be described.

Each arm terminates in a head 353. 'I'he head has a hollow valve chamber35| within it in which avalve 352 is seated. Air is supplied to thisvalve from a pipe 353 leading into the top of the outer'end of theradial arm 332. 'Through a packing gland 3 54 this air is transmitted tothe interior of the hollow shaft 343. From this shaft it extends-through the lateral ports 355 into the valve chamber 35|. As seen inFig. 33, the valve 352 is' what may be called a right angle valve inthat it turns 93 and in so doing it directs the air to either one of twooutlets. vThe valve has a passage 353 and another passage 351. In oneposition the passage 353 opens into the inlet 355 and directs air fromthe inlet to a port 353. When in this position a second port 353communicates by means of the other valve passage 351 with the exhaustpassage 333. The two passages 353 and 353 are controlled by adjustableneedle valves 33| and 332.

The passage 353 vleads out. as' appears in Fig. 29, to the top of acylinder 335 wherein slides a piston 333. `'Ihe passage 353 on the otherend communicates to the cylinder 335 beneath the piston 333.

' The piston has a piston rod 331 that passes through a cylinder head-333 and on the end of the piston rod is a head 333. At opposite ends ofthe head 333 are pivots 313 and 31| having nat ends 312 and 313 thereon.

Opposite ears 314 and 315 depend from 'the cylinder head. n these earsare pivoted two ware clutching means 313 and 311, having forked vendsthat come together about the ware finish to'grip the same. The arms 313and 311 have pivot means 313 and 313 extending outwardly throughopenings 333 and 33|, respectively, inl

the ears 314 and 315. The an'ns likewise at their ends have slots 332and 333 engaging non-ro- .tatably but slidably over the dat ends 312 and313 of the pivots 313 and 31|.

From the foregoing it is seen that elevation of the piston 333 lifts thepivots 313 and 31| and, hence. the inner ends of the arms 313 j .and311. Since `these arms are pivoted at 313 and 313 to the ears 3 -14 and315 that are not liited. the two arms pivot to cause their outer endsto`move together into clamping position.

Lowering the piston in like manner opens the arms to release the. ware.

To rotate the valve 352 a stem 335 projects out through a movable valvechamber head 333. A two-armed valve handle 331 is secured to the stem335. As shown in Fig. 3l, `the handle 351 i asaas'zs is eccentricrelative to the stem 335 and has ends 333 and 333.

For automatically rotating the valve handles. a collar 333 is adjustablysecured to the sleeve 333 by a set screw 33|. From this collar-projectopposite arms 332 and 333.having respectively the pins 334 and 395depending therefrom. It will be seen that the head 3411s rotated whilethe arms 332 and 333 remain still. Hence one of the valve handles 331will bring its end 333 to strike the pin 334 whereupon the valve will beshifted from its dotted line position in Fig. 31 tothe full lineposition, so thatthe piston goes up to close the arms 313 and 314together. The description will show that this takes place just at thetime a bottle is completed and is ready to be withdrawn. The bottle isthen transported by rotation of the head 341 to the right hand positionof Fig. 31, whereupon the pin 335 strikes the other end 333 of the valvehandle andreturns the valve to the position causing the, piston todescend, releasing the ware on to .a lehr chain, or the like.

In this shifting of the valve handle end 333 from the dotted lineposition of Fig. 31 to the full line position-thereof, the eccentricityof the handle causes the end 333 to be displaced outwardly of the arm343, so as to bein a path including the other pin 335. Likewise,shifting of the handle end 333 by the pin 395 causes the end 333 to bedisplaced inwardly to be in a path including the pin 334.

Consequently, this sleevel3| rotates with the drum. It will be remembered that the pipes |43communicate into .this sleeve -at intervals.

Above this sleeve, a cover plate 43| is secured to the column. 'Ihiscover plate has a circular upstanding channel 432 extending completelyaround it. and, as will be shown, divided into several differentcompartments. The ilrst compartment 433 is formed between a gate 434 anda gate 435. These gates fit snugly within the channel 432 and-are sealedtherewith by packlng washers as shown. There'is another such gate 433that extends for approximately 135 on the other side of the column.

Thev several gates areadjustable to determine the points of starting andending of the pressure and vacuum steps. Between the gates 435 and 433there is a.pressure chamber 431 and between the gates 434 and 433 thereis an inactive chamber 433. Fig. 3 discloses that the upper ends of thepipes |43 successively come into registry with the -several chambersmentioned.

l To demonstrate the adjustment of the gates. adescription of oneadjusting means will sufilce, as they are all the same. The gate 434 isshown in Fig. 8. It has on its outer edge gear teeth 4|3 withwhichengage the teeth of a gear 4||\ direction: and a set screw 4 |5 may betightened into a. neck asv shown to hold the gate-in its adjustedposition. In like'manner, the handle 4|6 a adjusts the gata los and thehandle m adjusts the gate 406.

There are an air pressure line 420 and a vacuum line 42| that arebrought' to a convenient point above the column 38.' The line 353connects into the pressure line 420, by a hose '422 sufliciently long topermit some rotary adjustment of the ware'take-out arm 332. 'I'he line420 enters the pressure chamber 401 in the member 402 by a verticalheader 423. A second header 424 leads from the pressure line into thecolumn 3B, and passes through the column to within an annular manifoldchamber 425 formed ,by a ring 420 in sealing relation with the column,but rotatablel therearound. At intervals around the manifold suitablefor the several blow heads of the finish molds are pipes 421 secured tothe `drum 15 as at 428, (Figs. 2, 8 and 9), to rotate therewith. 'Ihesepipes terminate outside the drum, and have `attached to them flexiblehoses 301, one leading to each blow head.

'I'he vacuum line 42| is connected into the channel member 402 in thevacuum lchamber 403.

Summary of operation InFig. 34, the blank molds appear in the middlecircle. At station A the gob is fed into the blank mold. Between thisstation and station B, the` vacuum is being applied, drawing the gob.down in the' blank mold and over the plunger to form the nish.

Between stations D and E, the transfer byinversiony takes place, the neck rings turning over to withdraw theparison from the open blank mold and insert it into the open finishmold. Between sta- The column 38 will remain stationary andwith it willremain stationary the cam 322 for operating the blow-down head, the cam268 for opening and closing the nish mold, the cam |49.for operating theplunger in the blank mold, the cam |2I for opening and closing the blankmolds, the closure plate 40| onthe air control means, the cams 226 forcontrolling the baiile plate, and the sleeve 330 of the ware take-outmechanism.

In order further to understand.` the mechanism, a single-charge of glassWil-l be carried through to completion. This glass is charged into theblank mold 4at, station A, as appears in Figs. 2 and 8. Immediately byaction of the cam roller |50 on the sloping cam track |5|, the plunger|39 tions E and F, the finish mold closes over the mediately applied totheA blank in the nish mold because of the automatic action ofthe tappetin the blow head. j This continues to take place between stations G andH, but during this periody the blank molds `are again closing, s'o thatjust willl move up to seat in its uppermost posi-tion. Then the conduit|46 will come into registry with the vacuum chamber 403 so that a vacuumwill be imposed through the conduit |46, the passages and |44, to thechamber |43, and thence up around the plunger to the blank mold beneathcontinue as the mold passes from the stationA 4toward the station B.The-plunger forms a beginning for the blow back.

At approximately the time the mold reaches the station B, the cam 228will act upon the rollwin b`a withdrawn from the mush of the battle- -byaction of the cam roller |41 in the cam |48.'

this action taking place while the passage |45 is Ybeneath the gate 405in the .air control chamber. Asl soon asl the passage |46 comes fromVnder the gate 405 and into the chamber 401, aix,`

pressure is suppliedwhich acts in the,` opening left by the plunger inthe glass and .forces the glass backwardly up until it strikes thebafile plate and contacts completely the walls of the mold. This actionis completed by the time the parison reaches the station C. Atapproximately the time it reachesstation C, its passage |46 moves underthe gate 406 in the air distribution chamber so that the air pressure iscut oif.

Shortly after passing' the station C, the cam roller 224' will be actedupon by the cam 228 to lift and return the baille plate off of the mold.As soon as this operation is completed, the cam |2|, acting on theroller |20, will open the blank mold sections. This will leave theparison inverted and supported by the neck rings.

In the meanwhile, at the station D, the nish mold sections are open andthey will remain open up to .the station E.

At approximately the station D, the cam roller |90 of the invertingmechanism will begin to ride upwardly in the cam track` |9| and the-parison will be transferred to the open nish molds at approximately thestation E. As soon as this inversion is complete, the cam 266 will forceout theplunger 263 and close the nish mold sections together about theparison. Shortlyv thereafter, and at approximately the station F, thearmv |95 of the neck ring opening cam |93 will strike the pin |96,turning the cam and opening the neck rings. -Before the arm |95 haspassed completely over the pin |96, the-cam roller |90 wil-l havereached the descending portion of the cam track |9| land will have begunthe reverting of the neck rings, so that they will have beenliftedcompletely away from the parison by the time the arm |95 hascleared and the spring |82 again closes the neck rings together.
